I personally love skate and I haven't seen many people protesting against it. Skateboarders use to be pretty nice, they move around in some areas that are used to them -or even prepared for them-, and also there are some other problems related to transport as the new scooters, the public spaces for bicycles, taxi vs uber, etc... that I feel more people are concerned about right now. It probably used to be a bigger thing, when the big crews of skaters started to come 10 years ago, but I never saw a neighborhood trying to kick them off! (which doesn't means that it never happened) What I saw it happened was the opposite, like in Nou Barris where the neighborhood maintained a DIY skatepark -that now is amazing, finally paid by the city hall- for 20 years and made it a symbol of social protest/resistance.
